Methods for the repair of damaged low k films are provided. Damage to the low k films occurs during processing of the film such as during etching, ashing, and planarization. The processing of the low k film causes water to store in the pores of the film and further causes hydrophilic compounds to form in the low k film structure. Repair processes incorporating ultraviolet (UV) radiation and silylation compounds remove the water from the pores and further remove the hydrophilic compounds from the low k film structure.

A fast line maintenance repair process for damaged composite structures includes the application of a pre-cured patch that uses a quick curing paste adhesive to bond the patch to the structure. The adhesive is cured at relatively low elevated temperatures provided by a chemical heat pack. The low temperature cure eliminates the need to dry out the part and permits the application of the repair in a hazardous environment. In a typical commercial airline application, airline maintenance personnel can install the repair at the flight gate. The repair is intended to restore the structure to a desired load capability in approximately one hour. The repair can be removed if need be with less overall damage than would occur upon removal of typical mechanically fastened repairs. All or some of the repair materials and tools can be provided in a portable kit.

The present invention provides an apparatus and method for an adaptive machining and weld repair process useful for repairing airfoils, particularly damage to an airfoil leading edge and tip. The process first machines away damaged portions of an airfoil. Filler material is then added to the machined area through a process such as laser welding. At this point, the actual profile of the welded airfoil is measured using a Coordinate Measuring Machine. This data is then used to generate a “deformation” profile, an airfoil profile that approximates the ideal shape of the airfoil. The airfoil is then machined using the date of the deformation profile to produce that shape. The adaptive technology minimizes the amount of stock on material that needs to be removed by hand. The technique thereby significantly reduces costly manual processing.

A method to repair Aluminum Nitride (AlN) substrates is disclosed wherein a frequency doubled Q-switched Nd:YAG laser is used to remove unwanted metallurgy. The substrate is place in a liquid filled work chamber which acts to prevent metallic species of AlN from forming. The repair site can be sealed with a novel polymer coating to prevent contamination or corrosion. Repairs can be made to buried or surface metallurgy.

A thin film transistor (TFT) liquid crystal display (LCD) panel, its array substrate, and its manufacturing method. Color filters are integrated on the TFT array, and color filter stacks are formed on the thin film transistors to replace a black matrix, thereby reducing manufacturing time and costs. The color filter stacks can be placed at the border of the display area of the panel to reduce light leakage. The border of the display area has a liquid crystal injection hole. To allow the size of the liquid crystal injection hole to be increased, and to reduce the light leakage at the hole, color filter blocks and overlapping metal layers can be used at the border of the display area. The color filter stacks and other dielectric layers need to be away from the welding points of repair structures to prevent dielectric layer bursts during a repair process. Storage capacitors can use the feature described above so that the color filters are positioned away from the overlapping portions. Welding is used to improve the electrical contact between the metal layers and the pixel electrode.

The invention relates to the field of communication and transportation, in particular to a ballastless track board lifting support. The ballastless track board lifting support comprises a threaded rod, a plurality of buckles, two fixing nuts matched with the threaded rod, and four supporting rods made of channel steel; the ends of two adjacent supporting rods are rotationally connected with one buckle, and the four supporting rods are connected end to end in sequence to form a quadrilateral supporting frame; the lengths of two adjacent supporting rods in the supporting frame are the same; the threaded rod penetrates through two through holes in one group of the symmetrical buckles in the support at the same time to be connected with the through holes in a sleeved mode, and the two fixing nuts are arranged at the two ends of the threaded rod to be used for positioning the two buckles; in another group of vertexes, one vertex is fixed onto a base board through one buckle, and the other vertex is fixed onto a truck board through one buckle. According to the ballastless track board lifting support, concentrated stress on the damaged track board in a lifting process is reduced, and therefore the possibility that the track board is damaged in a lifting repair process is further reduced.
